## Discrepancy

(CAN) WHEN THE LANDING GEAR WAS SELECTED UP AFTER DEPARTURE, ALL OF THE NR 2 HYD SYSTEM FLUID WAS LOST AND THE LANDING GEAR DID NOT GO UP BUT REMAINED DOWN AND LOCKED.  THE ACFT LANDED SAFELY.  MAINTENANCE INVESTIGATION REVEALED THAT THE RT LANDING GEAR DOOR SOLENOID VALVE FAILED WHICH RESULTED IN THE LOSS OF NR 2 SYSTEM HYD FLUID AND THUS THE FAILURE OF THE GEAR TO RETRACT.  THE SOLENOID VALVE WAS REPLACED AND HYD SYSTEM SERVICED, GEAR SWINGS CARRIED OUT AND ACFT RETURNED TO SERVICE.
